UNITED STATES PATENT OFFICE VEHICLE JACK APPLIANCE Maurice B. Hull, West Allis, Wis. Application August 11, 1934, Serial No. 739,385 2 Claims (Cl. 254-88) This invention appertains to motor vehicles, character, which will be durable and efficient and more particularly to a novel appliance therein use, and one that can be conveniently carried for. v in the vehicle without occupying much space.

With the use of balloon and so-called dough- With these and other objects in view, the innut tires considerable difficulty is experienced in vention consists in the novel construction, ar- -5 placing a jack under the vehicle frame to elevate rangement and formation of parts, as will be the same when a flat occurs. This is due to the hereinafter more specifically described, claimed small space left between the frame and the and illustrated in the accompanying drawing, in

Figure 1 is a top plan view of the improved l0 Therefore, one of the salient objects of my inblock, showing the same used in connection with vention is toprovide a novel device for increasing the supplemental base.

A further important object of my invention is letter A generally indicates my improved autothe p ov s o of a novel appliance use in 0011- mobile appliance, and B the supplemental base junction with motor vehicles embodying a solid which can be d th ith block of hard wood or the like, having an inclined My improved appliance A comprises 1m 30 face to permit the wheel of a vehicle to ride up on body 3 formed from hardwood or the like, and the block W the Vehicle is Started, the block the upper face thereof is provided with a downhaving a novel swinging foot normally positioned Wardly and forwardly inclined rf I which within the planes of h Blde Walls of t block leads to a top substantially horizontally dis'- when the block is not in use, and adapted to be posed Wall '2 upon which the deflated tire is swung at right angles to: the block when the block adapted to rest when the Wheel is elevated by isin use to effectively prevent the tilting of the riding up the inclined face H. If preferred block as the Wheel rides up thereon inclined face H can be corrugated or provided A further important object of my invention is with transverse ridges I3 to facilitate traction be- 40 the provision of novel means for forming a plutweenrthe tire and the block. 7 40 of blocks with Swmgmg feet mm a The lower face of the block is left flat for enh g i gg ggg ggz g gz gfi g figz gig gagement with the ground, and it 15 to be noted placed upon the market at a small cost, the fort t the rear end of the block also preferably mation of the blocks being such that a plurality mchnes fiownwardly 8 rearwardly as at 45 of the blocks can be conveniently packed in a so as to Increase f ase area 0 the Small package. One of the salient features of my invention A further object of my invention is the provision 15 t Provlslon of the novel .Swmgmg f of a supplemental platform for connection with Whlch 1S employed for p evehtlng lateral tiltmg the block for increasing the base area of the block P the'block w h same 13 m The swmg" 50 when the same is used on soft ground and the like, mg ot '5 5 Cut dl ectly Out of the rear lower whereby the block will not be readily forced into Corner Of the block, Whlch forms a fl y, 01' t ground notch, IS, in which the foot normally fits when A still further object of my invention is to prothe block is not in use. Thus, the foot I5 is not vide a novel motor vehicle appliance of the above only economically formed, but the same will lie 55 withinthe plane of the side walls of the block when the same is not in use.

A bolt H can be employed for connecting the foot with the rear end of theblock, and the bolt can extend entirely through the block and the foot. This provides a simple but eiiicient means for connecting thefoot with the block for turning movement.

When the block is in use the foot is turned at right angles thereto (as shown in Figuresl and 2), and thus thefoot will resist lateral tilting movement of the block. v

A length of fabric l8 can be secured to-the front edge'of the block, as at l9, and this pre vents the slipping of the block awayfrom the wheel as the wheel approaches the block.

In use of my improved device, should a flat occur and should the frame of the car be lowered to such an extent thereby that a jack cannot be placed under the frame, the block is placed in front of or in rear of the wheel carrying r thedefiated'tire, with the strap lying in the path of the tire.

The footlfi is-now turned at right angles, as shown-in the drawing, and the vehicle is driven backward or for-ward as the case may be (dependingon the position of the block), and the wheel --=,will'ride up on the block. This will effectively raise the'wheel and the frame to such a height th-atithe conventional jack can be placed under the frameandthuspermit the easy raising of the frame to permit; the removal of the tire. Obviously, when-the wheel is elevated by the jack the ,blockisremoved. g

In some instances, such as when the block is used in softer sandy soil, it maybe advisable to use :an additional base in conjunoti with theblock, and hence Ihave provided the novel base B. r V

This-base,Bis'preferably formed from sheet metal'and includes a top plate 26 and outwardly iflaredimarginalilanges 26. The plate can be reinforced by struckout ribs 22, the lower i aces of whicharefiattened for engagement with the ground. The'length of the base is substantially the same asthe'length of the block, but the-width of the base is considerably greater than thewidth of thebloc'k. V

As shown in Figure 2, the block can be placed directly on the upper surface of the base at the longitudinal center thereof, with the lower inclined edge of the block directly in rear of the front flange 2 I.

In order to couple the block with the base, the

block can be provided with a socket 23 into which is adapted to fit a struck-out tongue 24 formed on the top wall, or plate, 2d of the base.

The blocksare so designed that the same can be economically-manuiactured and so that the same will readily pack for shipment and occupy -a minimum amount of space.

In Figure 5 I have illustrated the means of forming a plurality of blocks from a single length oftimber 25 without waste. The dotted'lines on the piece of timber indicate the manner in which.

thelblocks can be out therefrom.

Changes in details may be made without departing from the spirit or the scope of this invention, but what I claim as new is:--

e 1. An attachment for motor vehicles comprising, a block formed from a solid piece of material having a bottom flatlface and an upper inclined face, the lower rear corner of the blocki;

havinga notch cut therein, and a'vertically disposed swinging foo-t mounted in said notch adapted to normally lie within the notch and flush with ing of the wedge when the same is in'use, a supplemental base for receiving the wedgehaving a width greaterthan saidwedge, and a struck-up tongue formed on the base, the lower face of said wedge having a recess therein receiving said tongue to detachably connect the wedge and the basetogether against relative niovementywhen the wedge. is in use.
